* Hold Price is the term we use to indicate the price at which our Super Investors are comfortable owning a security. It is the price of the security as of the portfolio date (usually quarter end). It's a reasonable indicator of a stock's undervaluation at that price, otherwise it would have been sold. We only provide this value when a security is owned by at least two Super Investors. In the case of reporting dates being different, we calculate a weighted average price.
